Coylon at 6,000 to 8,000 feet, collected in the Central Provinces by Thwaites
also by Drs. Maxwell, Wight and G. Thomson.
This plant is cliaracteiicd by tho small pointed leaves, short spikelets, long glames,
and slightly ciliate palea. Thwaites says it is used in Newera Elha as a fodder for
horses.

7,200 ft. in September 1890 in flower. Also by Beddome in 1873 on Anemudi Hill,
Anamaiais, at 8,500 ft.
This is probably tho smallest Indian species of bamboo, and it is characterized
by the l-flowered spikelets and short leathery imbricate loaves. Since the discovery by
Trimen of the flowers, Munro's suggestion of its relationship to A, Walkeriana no longer
holds good.
